I got the Deluxe Edition the other day, and I thought this was a better, perfect release of the animated adaptation than the previous two parts. The seamless combination of Parts 1 & 2 worked out well than I thought, and that is coming from someone who thought DKR HAD to be two parts because books 1-2 were one story, and books 3-4 were another. This combo, full version makes it feel like a full epic story akin to films we know with long running times. How they did this worked out well for me, with going to black after Joker's smile from part 1, and opening with the news debate on Batman that begins part 2 with the words "Three Months Later" on the screen. They cut out only one thing and that's the Sons of Batman news footage that opened part 2 before the debate. But that's fine. If you've seen Parts 1 and 2, would you pass up getting a full length Dark Knight Returns animated feature that is 2 1/2 hours? Neither would I.
The commentary was informative and I wanted to listen to it again when I popped that disc again. The best feature from the Deluxe Edition was the Frank Miller documentary, and I think you guys would agree. At an hour and 20 minutes; this goes from Miller, DC, and Batman from the late '70s, into how they were glued together to create DKR from the influences, the story, characters, down to how the colors were chosen and mixed together. They do reference DKR's influence on Batman post-DKR, like Grant Morrison's Arkham Asylum to Scott Synder's current run on Batman, to Burton's Batman to BTAS (which Timm looks at the camera and says "Thanks Frank!" lol) but they don't talk about Miller's Batman post-DKR; which is expected, because that isn't this documentary nor does this documentary feel incomplete after that info. The other features are the same as the other two parts, which isn't a bad thing to have a completed release, especially me who didn't buy either Part 1 nor 2 so this is great.
Also, the cards that came with it are really nice. The favorite is this one which should've been the cover to the Deluxe Edition:
This for me just seems to be a call back to this promo image from the comic:
